(54) WIRE BRUSH FOR CLEANING THE CLOSED

one

The invention relates to the cleaning of pipelines.

According to the main author. St. No. 250039 is known to be a wire brush for cleaning closed horizontal drainage from vegetation, which is made in the form of a casing with openings in which wire pieces are made in the form of brackets, which are fixed with a sleeve, which is pressed by nut 1.

However, the cleaning of drainage horizontal pipes is unsatisfactory because the drainage pipes sprout by the roots of vegetation along slots or holes located on top or from the sides, and the wire ruff moves along the Bottom of the drainage pipes and does not reach them with their wire staples, since the ends wire clips are located on a smaller diameter than the inner diameter of the drainage pipes. When the wire brush is moved during the cleaning of the drainage pipes along the bottom, its wire straps touch the irregularities of the drainage pipes in the form of slots, openings, and joints, which makes it difficult to continuously mix, drain, and hence clean. Cleaning horizontal drainage horizontal DRAINAGE FROM VEGETATION

The wire pipe leads only from the large roots of the vegetation, while the small roots of the vegetation remain inaccessible for it, since they pass unhindered between the wire clips.

The purpose of the invention is to improve the quality of cleaning and centering the ruff in the drainage pipe.

The goal is achieved by the fact that a wire brush for cleaning a closed

10 horizontal drainage from vegetation is provided with arcuate longitudinal elastic plates, the ends of which are mounted on the ends of the body with the possibility of movement along its axis, and their middle parts are located above the ends of the brackets.

The middle parts of the plates are made with a sharp edge.

The plates are tapered to the ends.

With this design of the wire wire, the wire is centered along the axis of the drainage pipes during their cleaning, and its wire straps approach directly to the places where the roots of the vegetation emerge from the slots or openings of the drainage pipes

which improves the quality of their cleaning, and when moving the wire ruff through the drainage pipes, it is not allowed to touch the wire clips to the slots, holes and joints of the pipes. Installing arcuate longitudinal elastic plates with the ability to move along its axis allows the wire ruff to overcome when moving forward or backward obstacles in the form of narrowing drainage pipes, displacing them relative to each other due to subsidence of the soil, and for thick roots of vegetation to include wire brackets wire cpuia work on their removal.

It is preferable to provide arcuate longitudinal elastic plates in the middle part with sharp edges, due to which additional drainage pipes are cleaned from small roots of vegetation that are not removed by wire wire staple straps.

In addition, the implementation of arcuate prodol1) 1x elastic and gastin in the middle part narrowing towards the ends provides better conditions for cutting off the roots of vegetation from the surface of drainage pipes.

FIG. 1 shows a wire ruff, longitudinal section; in fig. 2 - arcuate longitudinal elastic plate, scan.

The wire brush includes a housing 1, in holes 2 of which are placed pieces of wire, made in the form of brackets 3, which are fastened with a sleeve 4, preloaded with a nut 5. The housing is provided with an eye 6, and the nut 5 with a shank 7 with a threaded end on which is screwed when cleaning the drainage pipes, a metal tube or a removable eyelet 8 for attaching a wire or cable to it to move the wire ruff in the drainage pipes. Couplings 9 are placed on the tank 6 and the shank 7 in which arcuate longitudinal elastic plates 10 are fixed, so that the middle part 1 of the plates K) is above the ends of the wire brackets 3, and the plates K) along with the couplings 9 have the opportunity to recur along the axis of the housing 1 during deformation of plates K) at places of narrowing of drainage pipes or displacing them relative to each other due to the design of displacement of sleeves 9 on the edge 1 of the ends of housing 1. For unimpeded passage of the wire brush in the drainage pipes, the distance d between the ends of the wire wires Located on different sides of epnja axis mennje internal diameter drainage pipe, and the distance between the longitudinal elastic plates dia.metru d equal to the internal drain pipes. The installation of the wire clips 3 and the plates 10 together with the sleeves 9 is carried out depending on the internal diameter of the drainage pipes to be cleaned. For this purpose, the sleeves 9 are made of two halves, which are interconnected in a known manner. The edges of the plates 10 have pointed sharp edges 12 at an angle; which is determined in a known manner, and the plates 10 from the middle taper to the ends at an angle; which is determined depending on the length of the wire ruff, the distance between adjacent 0 rows wire staples. Plates 10 are made of heat treated sheet spring material.

The wire brush assembly is performed in this sequence.

Install the housing 1 in the vertical

position so that the inner cavity is open at the top, wire brackets 3 - into the holes 2 of the case, sleeve 4 - into the case, straightened the wire brackets and pressing them to the case, press the sleeve 0 4 with the nut 5, install arc-shaped longitudinal elastic plates 10 with couplings 9 to 6 and shank 7 and secured in a known manner.

Dismantling the wire brush is carried out in reverse order.

When cleaning the short drainage pipes, metal nozzles are attached to the shank 7, pushing the ruff into the sod and milling forward and backward and cutting off the vegetation root plexus and removing them in a known manner. When cleaning the long drainage pipes, a removable eyelet 8 is attached to the shank 7, to which a wire, a cable, etc. is attached; The wire or cable 5 is attached to the eyelet 6 and is passed through a known turf through the sod, a wire brush is pulled through the sod from the other end, as the vegetation roots are broken off and cut off, they are removed by a known method. The use of the invention allows to improve the quality of cleaning of drainage pipes, to improve the passage of the wire ruff through the drainage pipes, to ensure the centering of the wire ruff on the axis of the drainage pipes.
